LEED, or Leadership in Energy and Environmental Design, is a “green” building certification system. LEED was developed by the U.S. Green Building Council (USGBC) and provides building owners and operators with a framework for identifying and implementing practical and measurable green building design, construction, operations and maintenance solutions.

LEED uses a rating systems that recognize projects that implement strategies for better environmental and health performance to promote sustainable building and development practices for both commercial and residential design and construction.

LEED promotes a whole-building approach to sustainability by recognizing performance in key areas:

     • Sustainable Sites
     • Water Efficiency
     • Energy & Atmosphere
     • Materials & Resources
     • Indoor Environmental Quality
     • Locations & Linkages
     • Awareness & Education
     • Innovation in Design
     • Regional Priority
